Abstract
We consider limits of N = 4 super-Yang-Mills (SYM) theory that approach BPS bounds. These limits result in non-relativistic theories that describe the effective dynamics near the BPS bounds and upon quantization are known as Spin Matrix Theories. The near-BPS theories can be obtained by reducing N = 4 SYM on a three-sphere and integrating out the fields that become non-dynamical in the limits. I will present various subsectors including PSU(1,1|2) and SU(1,2|2) types of subsectors in this limit.
We finally analyse the symmetry structure of the sectors in view of an interpretation of the interactions in terms of fundamental blocks.
This is based on two publications: 2012.08532 and 2111.10149, and one work in progress.
